Abstract

| This chapter discusses electronic structure of metal surfaces. The surface-electronic structure is an important aspect of surface physics. In the jellium model the atomic potentials are smeared out into a uniform positive background. Despite its simplicity it has largely contributed to the understanding of the surface electronic structure of metals. Illustrations include average density distribution for the electron gas and various energy parameters occurring in the theory, and self-consistent results of Lang and Kohn for the charge density near a metallic surface calculated for various values of rs. The electrostatic potential and the effective one-electron potential for rs = 5 is shown. A weak electric field perpendicular to the surface accumulates the charge near the surface. This phenomenon is also illustrated in this chapter. |
